ADJUSTABLE MEASURE.

Specification of Letters Patent. Patentd Feb. 2 2, 1916.

' Application filed November 39, 1914. Serial No. 874,721.

To all whom it may concern:

Be it known that I, ARTHUR S. WHEELER, a citizen of the United States,residing at Biltniore, in the county of Buncombe and State of NorthCarolina, have invented certain new and useful Improvements inAdjustable Measures, of which the following is a specification,reference being had therein to the accompanying drawing.

This invention relates to. measures the capacities of which may bevaried at will, whereby a singl measure may be utilized for measuringdifl'erent quantities and the necessity of keeping a number of measuresof ranging sizes may be avoided.

The object of the present invention is to simplify and generally improvethe con struction of measures of this kind as heretofore used; toprovide a more reliable and more easily operated locking device forsecuring the parts of the measure together in each adjustment; and toprovide means for guidlng the ad ustable parts in their relativemovements which means alsoconstitutes a. part of the locking means.

Other objects will appear as the description proceeds.

The invention will be first hereinafter described in connection with theaccompanying drawings, which form a part of this specification, and thenmore specifically defined in the claims at the end of the description.

In the accompanying drawings: Figure 1 is a side elevation of a measureconstructed in accordance with my invention; Fig.2 is a central verticalsectional view of-the same, the movable bottom being illustrated in anintermediate position; Fig. 3 is. a top plan view, and Fig. 4 is anunder plan view of the device.

As illustrated, the measure may have a cylindrical wall or body Aprovided with a suitable handle B. The body may be made of thin metalreinforced at the upper and lower edges by heavier strips a and a, respectively, although any suitable body construction may be used.

On the inner surfac of the body A there are fixed a plurality oflongitudinal and preferablv axially extending ribs 0 which may beV-shaped in cross section, as illustrated, and which are spaced apartatsuitable intervals around the entire circumference of the body. Threeequally spaced ribs,

C will answer my purpose very well, but more of them may be used inlarge measures.

The bottom D of the measure is. fitted snugly to slide within the body Aand may be provided with an upwardly extending peripheral flange clhaving grooves cl to accommodate and closely fit around the ribs C. Byreason of this construction the ribs serve as guides for the bottom andprevent the latter from being rotated within the body of thev measure.The provision of the extending peripheral flange tends to preventsagging or twisting of the bottom in the body between adjustments.

The ribs C also constitute a part of the locking means for securing thebottom in its various adjustments, and to this end said ribs. areprovided with spaced notches or transverse slots 0 opening at theirinner peaked edges, see Figs. 2 and 3. The notches in each of the ribsare spaced the same distance apart' and corresponding notches in eachrib are arranged on the same level, thus providing a series of lockingnotches on different levels within the body of the measure. Asillustrated, each set of such locking notches comprises three, one ineach of the thre ribs which are eveny distributed around the body. p

The other member of consists of a cam plate E. centrally pivoted to. theunder face of the bottom D by a suitable pin orbolt F and having aseries of notches e in its periphery, corresponding to the ribs C, sothat said notches 6 may be brought into alinement with said ribs whenthe bottom is to be moved from one position to another. To secure thebottom in a desired position, the cam plate E is turned the lockingmeans of one. of the sets in the ribs (1. A finger piece Gr projectsfrom the under surface of the cam plate for turning the same. Therotation of the cam plate may be limited between locked and unlockedposition in any suitable manner, as bv the bolt H projecting from thebottom D through an arcuate slot K in the cam plate. Said bolt H may befitted with a nut h and washer 71.. whereby the cam plate may be clampedto the bottom D in locked position to prevent said plate from workingout of the notches in the ribs when the measure is in use.

It will be observed that the use of three or more ribs evenlydistributed around the body of the measure provides ample supplate, sothat said plate can be clamped in locked position after adjustmentwithout removing the hand from the lower end of the measure.

Having thus described, my invention, what I claim and. desire to secureby Letters Patent of the United States is 1. In an adjustable measure,the combina tion with a body, of a bottom adjustable in said body,guiding means for the bottom fixed to the interior of the bodytransversely of the plane of the bottom, said means holding the bottomagainst rotation, and means coiiperating with the guiding means forlocking the bottom in adjusted position.

2. In an adjustable measure, the combination with a body, of a bottomadjustable in said body, a plurality of spaced ribs fixed in the bodytransversely of the plane of the bottom and having a series of notchesarranged parallel to said plane, and a rotary locking member pivoted onthe bottom and adapted to engage notches in all said ribs at the. sametime.

3. In. an adjustable measure, the combination with a body, of a bottomadjustable in said body, a plurality ofribs fixed at intervals .aroundthe interior of the body transversely of the plane of the bottom andhaving a series of notches arranged par: allel to said plane, and alocking member pivoted centrally of the bottom and having cam portionson its periphery to interlock with notches in all the ribs at thesametime.

4. In an adjustable measure, the combination with a body, of abottomadjustable in said body, means for preventing the bottom from turning inthe body, and rotary means on the bottom forlocking the same in itsvarious adjustments.

5. In an adjustable measure, the combination with a body, of a bottomadjustable in said body, rotary means for locking said bottom atdifferent adjustments, and separate means for clamping said lockingmeans against working out of locked position in use.

6. In an adjustable measure,'the combination with a body, of a bottomadjustable in said body, a rotary locking device pivoted on the bottomand having an arcuate slot Copies. of this patent may be obtained forfive cents each, by addressing the Commissioner of Patents,
